Ive said it before and I’ll say it again. Recon is the “Autistic Paganism”.
It requires us to obsessively research and absorb vast swathes of trivia and historical information about a single narrow topic(depending on the specific form of recon or polytheism you’re attending to).
We love ritual and following formulae for our ritual
We follow daily and holiday routines some of which are millenia old
We have a “black and white” view of reconstructionism: There is a right and wrong way to do things. We can get pretty cagey about it *cough Asatru Lore*
We like strictly delineated social rules(especially those theodish folks)
We hate change, so we reconstruct ancient practices
